Abstract: In this paper the solar soft X-ray events with importance X, proton eventsand the corresponding radio alow varying component (SVC) as well as radioevents generated from AR5395 and AR5629 in March and August, 1989, are analysed respectively comprehensively. The main results are as follows:1. The X-ray events with importance X occurred basically on the backgroundlevel C2 of X-ray emission, which are well correlated with spectra index α_s at highfrequency side of SVC spectrum, for example, level C2 corresponds to-2 < α_s< 0 for AR5395.2. The importance of X-ray event is proportional to the harder spectral indexand the ratio of peak flux density at high frequency to that at low frequency ofdouble peak spectrum, and inversely proportional to the spectral index between8.8GHz and 4.995 GHz of mono tonicaly rising spectrum.3. Proton event may also be related with the spectral depth T≤0. 5 at 2. 695GHz, except type U spectrum of radio event.
